java-home

In my build.xml file, I have these lines: <property environment="env"/> <echo message="JAVA_HOME is set to = ${env.JAVA_HOME}" /> On some machine, this would print "JAVA_HOME is set to = /usr/jdk1.6" But on some others, it would print this "JAVA_HOME is set to = ${env.JAVA_HOME}" Does anyone know what might cause this? Thanks The message tells you that Ant was not able to resolve the property env.JAVA_HOME ; this means that the environment variable JAVA_HOME was not set in that machine. You can usually find on your system (if you're Unix) where the actual ant command lives by doing either

I am trying to install some software (Shibboleth) in Ubuntu 14.04. I already have Java 7 OpenJDK installed in /usr/lib/jvm/ , and I have these lines in /usr/environment JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64" export JAVA_HOME If I type echo $JAVA_HOME I correctly get /usr/lib/jvm/java-7-openjdk-amd64 . However, when I try to install Shibboleth I always get Error: JAVA_HOME is not defined correctly. Cannot execute java . Interestingly, if I type java command it works (it refers to /usr/lib/java which is a link to the right one). However, when I try to run bash bin/install.sh of Shibboleth

I restart the PC - and I think I can check which version of Java my machine is pointing at - but it still points to the older version of Java e.g v1.5.0_16 Can you help me rejog my memory on correct setup for Java JDK? Jigar Joshi You need to reset your path variable to point to 1.6 something like Additionally, make sure the variable JAVA_HOME is also set with the above location. JAVA_HOME is used by other applications, such as Tomcat. Windows just

I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory ( /usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I

I am on the verge of releasing a project but it seem JAVA_HOME is been inconsistent. Maybe it's been overridden somewhere else?
